After Micro swiss DD upgrade,Extruder skips steps

lui2004

@Veti nothing special, finetuning temptower,retract settings
all seems fine but with the M207 i have problems

Veti

so without m207 its extruding again?

lui2004

@Veti yes with normal retractin from slicer all fine

with M207 no extrusion , it will print only the base and not the 2 towers for retracting test

Edit:

now i have see what cause that no filament come out.
after retract its during to much time to reload the filament
i dont know which parameter can set to solve it

@Phaedrux @Veti

i forgot to check '' use realtive E distances '' in the printer Settings, now it works.

do i need to go higher with my retract settings ?

at this moment i got this settings for firmware retractions:

M207 P0 S1.5 R0 F2100 T2100 Z0 ; Firmware Retraction

or i need to print the retractions stl and post pictures ?

thanks

Veti

start the print. if its stringing increase the retraction setting in the console while printing.

lui2004

@Veti ok

with which one i begin ? retraction Speed,distance ... ?

Veti

distance

lui2004

@Veti ok

right now i am at:

M98 P"0:/macros/Tuning/Report Current Retraction Settings.g"
Tool 0 retract/reprime: length 0.25/0.25mm, speed 35.0/35.0mm/sec, Z hop 0.00m

without stringing,is it good ?

Veti

you have to decide that by yourself if you are happy with the result.

lui2004

@Veti

it looks great !

but one question why with slicer retraction i have 1.5mm and with firmware retract i have 0.25mm ?

the distance are good ,now i will check with speed right ?

Veti

yes you can, but 35mm/sec is a good speed for retraction

lui2004

@Veti

ok i will leave so !

i will reprint the benchy to check if its ok

lui2004

@Veti

i want print the benchy but the first layer adhesion is terrible what i can do now ? before it was all good

Veti

can you post a picture of the result?

lui2004

@Veti

I dont have adhesion for the first layer so i dont have printed

Indint know if i calibrate the EM again or z-offset

Phaedrux

Clean the bed maybe?

lui2004

@Phaedrux allready done with iso....

I will check this

@lui2004

Wish I had of caught this post before you went through everything. The MicroSwiss DD can't use a pancake style motor. This is due to the MS DD not being geared. Use a 42-34 Nema 17.

I ran through all the same problems and was immediately fixed by putting the stock motor on, a 42-34.

Veti

you are right @RyanP

lui2004

@RyanP i have the original one here 42-40
